Liu Wei, a Chinese artist goes around the streets of Beijing on June 4th asking people ‘What Day is it today?’ hoping for an answer on the lines of ‘Today’s the 16th anniversary of the Tiananmen Square Massacre’ but what he gets instead is a lot of ‘I don’t know’'s from the people whose faces clearly say otherwise.
In 2017, the people old enough to be grad students truly don't know about it because the Party has successfully erased it from public discord within the mainland.
Chung Kai-Shek is the romanization of 蔣介石 in Cantonese. If those post-docs weren't native in Cantonese, there's almost no way they can connect the pronunciation of Chung Kai-Shek back to 蔣介石.
In another romanization system used by ROC, 蔣介石/蔣中正 is Chiang Chieh-shih/Chiang Chung-cheng. Mainland Chinese can probably recognize them, but no guarantees.
